PSG president Nasser Al-Khelaifi gave the club's stars a dressing down at their training session on Friday amid a dreadful run of results.
The French giants have struggled to regain their mojo after being knocked out of the Champions League by Bayern Munich. They have lost two successive games, though still hold a comfortable lead in the Ligue 1 title race.
They were beaten by Lyon on Sunday, with Al-Khelaifi now taking drastic action in a bid to spur PSG out of their current slump. Boss Christophe Galtier revealed the Qatari had attended training on Friday and gave a speech in the dressing room.
